Introduction: The presence of greenhouse gases in the Earth’s atmosphere last year reached its highest levels since pre-industrial times, a report released by the United Nations World Meteorological Organization (WMO) warns recently. Even if we managed to halt our greenhouse gas emissions today, and this is far from the case, they would continue to linger in the atmosphere for decades to come and so continue to affect the delicate balance of our living planet and our climate. The latest edition of WMO’s Greenhouse Gas Bulletin also notes that the rate of increase of greenhouse gases has recently accelerated. Carbon dioxide, methane, and nitrous oxide are the three main contributors to greenhouse gasses, with carbon dioxide’s atmospheric abundance rising by 39 per cent since the start of the industrial era in about 1750. According to the same report, the 20 years to 2010 saw a 29 per cent increase in radiative forcing, the warming effect the gases have on the Earth’s climate, from greenhouse gases, with carbon dioxide accounting for 80 per cent of this increase. Human activities, such as fossil fuel burning and agriculture, are major emitters of greenhouse gases, which trap radiation within the Earth’s atmosphere, causing it to warm and spur climate change. Because of that, our globe is undergoing major changes at an unbelievable rate. We can see from satellite images and research that the ice caps are melting faster, our sea levels are rising, and weather patterns are changing. We are experiencing more water shortages and we will see hurricanes, typhoons and cyclones increasing in ferocity and frequency. The deserts will expand and the world will ultimately have difficulty growing enough food. Without doubt, we have to change the way we live. Thousands of scientists from a hundred countries are working ways to reduce greenhouse gases and make a less harmful impact on the environment. The growing awareness of the greenhouse...

The Factors Affecting Greenhouse Gas Emission in the Livestock Industry
People around the world have become very aware of the changes our world is going through on a constant basis. One of the biggest subjects people are talking about is global warming and how the human race is the number one cause of it. In more than one way this is unmistakably true. From the daily activities of driving gasoline powered...

...wonder why disastrous weather events like super-storm Sandy continue to increase in their frequency and severity? Many modern scientists attribute these dangerous environmental trends of global warming to the ‘greenhouse effect’.
The ‘greenhouse effect’ results from greenhousegases such as carbon dioxide rising into the atmosphere, trapping infrared radiation from the sun, and emitting ultraviolet radiation that can puncture the...

...﻿Greenhousegases
Carbon dioxide is a colourless, odourless gas that makes up .04 percent of the earth’s atmosphere. It’s released by the breakdown of organic materials, by animals when they respire, and by the burning of fossil fuels. Carbon dioxide isn’t toxic—after all, we exhale it with every breath and use it to make our drinks fizzy. However, carbon dioxide is considered a pollutant because, as a greenhouse (heat-trapping) gas, it’s a...

Introduction
A greenhouse (also called a glasshouse) is a building in which plants are grown. These structures range in size from small sheds to industrial-sized buildings. A miniature greenhouse is known as a cold frame.
A greenhouse is a structural building with different types of covering materials, such as...

...green chemistry, the most common route is the use of greenhouses. “Greenhouses are structures used to grow plants under protected conditions” (Albright, 2004). This topic was chosen to inform readers about the history, purpose, advantages, disadvantages, heat management, and future improvements of greenhouses. However, it was mainly selected to advise individuals about the technology that greenhouses involve and require.
Presently,...

...GREENHOUSE EFFECTS﻿
IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhousegases, and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2]
Solar radiation...

...GreenhouseGases: Carbon dioxide (CO2) is a greenhouse gas in the atmosphere that may raise average temperatures on Earth. The burning of fossil fuels could be responsible for the increased levels of carbon dioxide. If current trends continue, future concentrations of atmospheric carbon dioxide in parts per million (ppm) could reach the levels shown in the accompanying table. The CO2 concentration in the year 2000 was greater than it had been at any...
